The paper reports new records of aphyllophoroid fungi on the north-western coast of Lake Ladoga. Surveys in 2020 and 2023 in the Sortavala and Suojarvi Districts, Republic of Karelia, detected 143 species of aphyllophoroid fungi, including records of 103 species from Ruskeala Village area and 86 species from Suistamo Village area. Skvortzovia georgica was found in the Republic of Karelia for the first time. Eleven species are novel findings for the biogeographical province Karelia ladogensis (Ceriporia reticulata, Polyporus pseudobetulinus, Porotheleum fimbriatum, Skvortzovia georgica, Typhula crassipes, T. erythropus, T. lutescens, T. quisquiliaris, T. sclerotioides, T. setipes, T. uncialis). Four species of aphyllophoroid fungi listed in the Red Data Book of the Republic of Karelia (2020) were located (Lentaria afflata, Leptoporus mollis, Polyporus pseudobetulinus, Postia placenta). We also encountered 19 indicator and specialist species of biologically valuable forests. The records are supported by herbarium specimens deposited in KarRC RAS Herbarium (PTZ). Information on habitats, substrate affiliations, and occurrence is provided. Most of the species (72) were found on deciduous wood, and 63 species grew on coniferous species. Spruce was the substrate for 56 species, aspen for 28, gray alder for 27, birch for 23, and pine for 15 species. These results are important for monitoring in the Northern Ladoga region.
